What does the military test for?

I can't tell you.

It's not because I'm being a jerk. It's because they change what they look for all the time. They start out by testing for the Big 5--THC, cocaine, amphetamine, methamphetamine and PCP. They then test for two other drugs. The Army lab at Fort Meade is certified to test for 29 drugs--the five I mentioned plus 24 others. The two additional drugs aren't even known to the test operator until the morning the tests are to be run.

I think you can see why. The Army knows about the internet--the Army (guess who owns DARPA?) INVENTED it! They know about chatrooms and bulletin boards, and if they decided to test for...oh, benzos...over these next two weeks, someone would be certain to get on the Internet and post to a bulletin board, "hey, no one in the Army should do benzos for the next two weeks."
